我们尝试使用Node.js（和Mocha）作为测试框架，通过https测试针对内部服务器的API调用。 我们使用以下节点模块：Mocha，Restify和Should来执行这些测试。
当我们运行mocha testFileName.js时，我们得到的主要错误是：
[2013-06-19 14:16:28.105] [ERROR] console - FAIL: Received error! [Error: UNABLE_TO_VERIFY_LEAF_SIGNATURE]

搜索google和stackexchange后，似乎我们有证书问题。从那里我们安装了内部CA'公共'证书，以及我们的应用正在使用的实例特定认证（有多个重定向要通过），到
/usr/local/etc/openssl/certs, legacy: /System/Library/Keychains/X509Anchors, /Library/Keychains/System.keychain, as well as in Keychain through the gui to our login and System keychains. However, we're still not getting anywhere.
在这些地方安装证书之前，我们无法在命令行上没有证书错误的情况下“卷曲”我们的网站;但是，现在安装它们我们没有错误，但节点仍然爆炸。
我们尝试过多个版本的Node，OpenSSL，以及各种安装方法，包括下载软件包和使用自制软件。
电脑资讯：
Node.js是否使用自己的（捆绑的）OpenSSL版本而不是本地机器上安装的版本？ 如果是这样的话，它在哪里寻找证书？ TLS.js能告诉Node寻找其他地方的证书吗？ 是否采用务实的方法来覆盖所使用的证书;似乎我们可以使用这样的选项：
var options = {
ca: fs.readFileSync("[path to our CA cert file]"),
requestCert: true,
rejectUnauthorized: true
};
var req = https.request(options, function(res) {
...
});
但这会产生同样的错误。

<强> UNABLE_TO_VERIFY_LEAF_SIGNATURE
问题是您尝试从具有错误或不受信任的SSL [安全套接字层]证书的存储库安装模块。如果您在一家自行签署内部存储库证书的公司工作，这种情况并不罕见。
要解决此问题，可以运行以下命令：
npm config set strict-ssl false
作为一种最佳做法，明智的做法是将其设置为真正的后记，这样您就不会意外安装一个您实际上不信任的不受信任的模块。

回答有关使用捆绑版OpenSSL的第一个问题：
节点在编译期间根据crypto api的需要生成静态对象。
例如，加密API需要以下OpenSSL函数调用：

因此，当编译node时，它会创建一个静态对象，该对象仅包含它需要的那些函数。这是来自核心node.js团队的设计决策，它允许最小的膨胀。
如果您希望将节点链接到OpenSSL的行为从静态更改为共享，您可以从源代码编译node.js，如下所示：
$ curl -k http://nodejs.org/dist/v0.10.26/node-v0.10.26.tar.gz | zcat | tar -xf -; cd node-v0.10.26; ./configure --shared-openssl
回答第二个问题：
TLS模块使用您指定的证书。您可以使用OpenSSL测试服务器及其相应证书的功能，如下所示：
openssl s_client -connect server:port
这将为您提供有关您的证书链的详细信息，这些详细信息使用curl等工具无法轻松获得。
简单的修复应该是将此选项设置为false，因为您的测试客户端未配置为发送任何客户端证书。
var options = {
/* ... */
rejectUnauthorized: false
/* ... */
}
关于“实际问题”，它源于客户端证书存储，其可信CA源（浏览器SSL证书管理器）和服务器证书的组合，以及客户端不信任其CA.
希望清除它。
答案 2 :(得分：3)
尝试类似：
cas = [fs.readFileSync("[path to our CA cert file]"],
https.globalAgent.options.ca = cas;
取自http://permalink.gmane.org/gmane.comp.mozilla.identity.devel/3762
对我来说，所有其他解决方案都失败了，似乎需要在全局代理上应用。
答案 3 :(得分：2)
有时，如果您使用带有某些代理配置的网络，则npm无法验证包签名。
试试这个，
npm set strict-ssl false
取自https://github.com/Leaflet/Leaflet/issues/2860
之后，
npm cache clean --force
它会起作用。我试过这个。
答案 4 :(得分：2)
要解决此问题，请使用
安装模块node_extra_ca_certs_mozilla_bundle
npm install --save node_extra_ca_certs_mozilla_bundle
然后在代码中使用它：
const fs = require('fs');
const https = require('https');
https.globalAgent.options.ca = yourCertificatePEMcontent + fs.readFileSync('node_modules/node_extra_ca_certs_mozilla_bundle/ca_bundle/ca_intermediate_root_bundle.pem');
这种方法对我有用。
答案 5 :(得分：0)
您可以在运行命令时尝试添加--insecure选项吗？
答案 6 :(得分：0)
我遇到了我的其他问题，都是由https完成的。当我与节点客户端连接时，会收到这些错误。对我来说，解决方案是使用中间证书。
var key_content = fs.readFileSync('./resources/certificates/foo/foo.es_private_key.key');
var cert_content = fs.readFileSync('./resources/certificates/foo/foo.es_ssl_certificate.crt');
var ca_content = fs.readFileSync('./resources/certificates/foo/_.foo.es_ssl_certificate_INTERMEDIATE.crt');
var options = {
key: key_content,
cert: cert_content,
ca: ca_content
};
var server = https.createServer(options, app);
